Patent CA-2152081-A1 (CA)
Title: Toxic material disposal
Inventor: DONECKER PETER
IPC: B09B3/00
Filed: 1993-12-17
Abstract: A process for the treatment of toxic materials, for example, inorganic compounds, halogenated organic compounds such as poly-chlorinated biphenyl (PCBs), dioxin and dichlorodiphenyl trichloroethane (DDT) and chemical weapons such as Sarin and mustard. The process is based on the discovery that mechanical activation can induce chemical reactions which break down the molecular structure of toxic materials and form products which are simple, non-toxic compounds.  The process involves subjecting a mixture of a toxic material and a suitable reagent to mechanical activation to produce a non-toxic end product or products. Mechanical activation is typically performed inside a mechanical mill, for example, a ball mill. Ball milling of various toxic materials with appropriate reagents was found to result in virtual total destruction of the toxic starting material.

Abstract: The invention comprises an elevator electrical component having a front plate that has no visible fasteners, the component being removable by a key. The elevator component has a housing attached to a face plate, a number of flexible arms attached to and integral with the housing, the arm(s) causing the housing to interfere with an opening in the elevator or the landing upon insertion or removal of the housing from the opening, the arm being movable in two directions to avoid interference with the opening upon insertion or removal of the housing from the opening, a visually inconspicuous accessway in the face plate for allowing access to the arm, and a key for extending through the accessway and simultaneously moving the arm or arms inboth directions to allow the component to be removed from the opening without interference by the arm(s). The component may include a shaped projection that causes the housing to be specially manipulated to remove the housing from the opening even after usage of the key. The component may also include an obstruction to prevent the arm or arms from not interfering with the opening unless the key is used.

Patent CA-2184566-A1 (CA)
Title: Underground contamination in situ treatment system
Inventor: KIEST JOHN L
IPC: B09C1/00
Filed: 1996-08-30
Abstract: A system and process for delivering fluids into subsurface contaminated soil and groundwater to enhance in situ microbial degradation of contaminants.  The equipment includes a tank with means for creating and maintaining a slurry in the tank, which tank is connected to a pressure pump which selectively feeds fluid at relatively low volume and high pressure to a hose and ground penetration lance with a nozzle for expelling the fluid. Microorganisms, soluble and insoluble nutrients, surfactants and chemical peroxygens and also gases can be delivered into the subsurface with this system.  For example, a site may be treated using a fluid consisting of a water slurry of magnesium peroxide, with urea, ammonium phosphate, ammonium sulfate or a mono-potassuim phosphate and/or organisms with attributes which can attack and brake down the hydrocarbon pollutants into intermediate by-product and eventually into harmless carbon dioxide (CO2) and water depending on the particular hydrocarbon, the nature of the underground geologic composition, and the site geologic chemistry conditions. The process consists of inserting the fluid from the tank by water-jetting the lance's free end generally vertically from the surface down through the zone.   The high pressure fluid liquifies the soil in front of the lance nozzle allowing the lance to be easily advanced by hand into the subsurface while low volume prevents driving the contaminants.   The fluid is forced outward transversely along the lance's path to form a generally cylindrically shaped volume, or core of infused fluid.   The lance is then removed and inserted vertically a short distance away from the initial insertion.   The process is then continued over the entire zone.   In this manner, fluids that stimulate the biodegradation of the petroleum hydrocarbon or chemicals are dispersed and infused throughout the zone.
